  <h1>🛰️ iframe 操作</h1>

<p><code>&lt;iframe&gt;</code>元素是一种特殊的元素，它既是元素，也是页面，因此独立一个章节对其进行介绍。</p>
<p>与 selenium 不同，DrissionPage 无需切入切出即可处理<code>&lt;iframe&gt;</code>元素。因此可实现跨级元素查找、元素内部单独跳转、同时操作<code>&lt;iframe&gt;</code>内外元素、多线程控制多个<code>&lt;iframe&gt;</code>等操作，功能更灵活，逻辑更清晰。</p>
<p>我们使用菜鸟教程在线编辑器来演示：</p>
